The birds

Birds are known as bipedal vertebrates whose body and wings are covered with feathers and they have a bony beak in front of the face without teeth .

 Most types of birds are able to fly and fly in the air at different altitudes and for long distances , while there are some types of birds that cannot fly , and many of them can run , .jump , swim, dive and walk

birds characteristic

There are characteristics of birds, the most important of which are 

Vertebrate animals with skeletons*

Warm-blooded, adapted to live in different conditions, on land, in water and in the air, and at different temperatures*

The body is covered with feathers*

The sense of smell is weak compared to most birds, but the sense of sight is very strong*

All birds lay eggs*

Birds adapt to the environment

There is a set of adaptations in the bird's body, which helped the birds and gave them the ability to fly, and among these adaptations is the lightness of their skeleton in

relation to their weight.

The structure and structure of the bird's bone differs from the bones of other vertebrates, as the bones of birds are characterized by a low-density reticular structure.

Many birds exhibit ecological behavioral adaptation, and the method of adaptation varies with the species of bird and the surrounding variables and conditions.

Some birds show behaviors that adapt to the cold weather, and other types adapt to high temperatures.

Migration is also a manifestation of the behavioral adaptation of animals. For example, we find flocks of species of birds that migrate south in the winter, where more food is available.
